摘　　要：在天气条件比较恶劣的情况下,使用传统EBA方式进行汽车刹车,由于防滑系数是固定的,将造成刹车距离过长的缺陷,从而降低了汽车的安全性能。因此,提出了一种基于模糊控制动态模型的汽车智能防滑刹车系统。建立汽车智能刹车模糊控制动态模型,获取刹车控制参数,计算汽车行驶路面防滑系数,对智能刹车模糊控制模型中的参数进行动态调整,从而缩短在恶劣天气情况下汽车刹车时需要行驶的距离。实验结果表明,这种算法能够有效缩短恶劣天气下汽车刹车的距离,取得了令人满意的效果。When the weather condition is poor,by the use of traditional EBA way the brake,due to prevent slippery coefficient is fixed,will cause the brake long distance defects,which reduce the safety performance of the car.Therefore,this paper puts forward a dynamic model based on fuzzy control of the intelligent antiskid brake system.Establish the intelligent braking fuzzy control the dynamic model,get the brake control parameters,calculation automobile driving road surface prevent slippery coefficient,fuzzy control model of intelligent brake of the parameters of the dynamic adjustment,which can decrease in bad weather situation to the brake driving distance.The experimental results show that this algorithm can shorten the bad weather automobile braking distance,satisfactory results have been obtained.
